Lowest unit cost in the standard range
One body seam instead of four panel seams means less sewing time and less fabric waste per bag.

Top
Open top, duffle top, filling spout, with or without skirt

Fabric & coating
140 to 200 GSM woven PP, optional lamination
What it settles: Explains what the seamless body actually changes — discharge cleanliness, seam count, cost per tonne — and where the construction stops being the right answer.
Best for: Free-flowing powders, granules and pellets loaded to 500-1,500 kg where cost per tonne, cleanliness of discharge and filling speed matter more than shape retention.
Not the answer when: The buyer needs stackable, dimensionally stable bags, or a rectangular footprint on the pallet, or the material is a fine powder that needs a baffle-stabilised body.
Confirm before quoting: SWL and safety factor, filling and discharge method, liner requirement, UV exposure during storage, and the printing/artwork deadline.
/ Overview & Principle
HOW THIS BAG IS BUILT
The body is woven on circular looms as a continuous tube and closed with a base seam, so there is no vertical side seam in the body. Lifting loops are sewn into the top seam (four-corner or cross-corner), and the top and bottom openings are built to the filling and discharge method the customer uses.
Because the tube is closed rather than panel-sewn, the bag has one body seam to control instead of four. This is why tubular bags are usually the most economical construction per tonne of product moved, and why they are frequently chosen for free-flowing mineral and chemical powders.
Operational summary:
A seamless circular woven bag for free-flowing powders and granules; the lowest-cost standard construction where stackability is not the deciding factor.
/ Features
KEY DESIGN ADVANTAGES.
Smooth interior for free-flowing product
With no internal side seams, powders and granules discharge more completely and the interior is easier to clean and inspect.
Fewer seam paths for leakage
Fine powders escape at seams before they escape at fabric, so fewer seams means fewer places to control.
Fits standard filling equipment
The circular body holds its open shape on a filling spout, which keeps manual and semi-automatic filling cycles short.
Even load path through the body
With no vertical side seam, lift load travels through the woven tube rather than along four corner seams, so fewer load paths depend on stitching.
Takes a tube liner without folds
A round body accepts a tubular liner with no corner creases, so lining and closing stays simple where a fine powder needs a barrier.

- SWL / Safety Factor
- 500 kg to 1,500 kg SWL Safety factor and test protocol confirmed at quotation stage.
- Top
- Open top, duffle top, filling spout, with or without skirt Dust control at filling often decides this.

- Lifting loops
- Four-corner, cross-corner, single-loop, two-loop Loop type follows the lifting equipment at the customer's site.
- Fabric & coating
- 140 to 200 GSM woven PP, optional lamination Coating is added for moisture and dust control rather than for strength.
- Liner
- None, loose PE liner, glued-in liner Liner gauge and closure method confirmed against the material.
- UV stabilisation
- Standard UV package; extended package on request Outdoor storage duration is the input we need from the buyer.
- Printing
- 1 to 4 colours, flexo Artwork and colour reference required before sampling.
- Packing
- Bales of 10-20 pcs, or cartons Packing choice affects container loading and unloading labour.

PERFORMANCE, TESTING & LIMITS.
1. Performance & working envelope
| Rated range | Rated for 500-1,500 kg SWL in standard configurations, with the fabric and loop construction set by the confirmed SWL and safety factor. Performance figures in a quotation apply to the confirmed specification only; a change of fabric, loop type or coating is treated as a new specification. |
|---|
2. How it is validated
| Testing | In-house checks cover fabric weight, seam strength and bag dimensions on each production run, with first-piece and final inspection recorded against the order. Third-party testing is arranged where the buyer's market or their own procurement process requires it, and is quoted separately. |
|---|
3. Limits
| Where it is not the answer | The circular body bulges as it fills and does not hold a square footprint, so this construction is a poor choice where pallet stacking height and stable columns matter. It is also not the right answer where the filled bag has to hold a defined shape in a display or automated handling system. |

Selection & Purchasing Guidance
- Best For:
- Free-flowing powders, granules and pellets loaded to 500-1,500 kg where cost per tonne, cleanliness of discharge and filling speed matter more than shape retention.
- Consider Alternatives When:
- The buyer needs stackable, dimensionally stable bags, or a rectangular footprint on the pallet, or the material is a fine powder that needs a baffle-stabilised body.
- Must Confirm Before Quoting:
- SWL and safety factor, filling and discharge method, liner requirement, UV exposure during storage, and the printing/artwork deadline.
